Gree AC error H1

Although they are famed for their high quality, they are not without issues. Some Gree AC units are known for being faulty and these faulty Gree AC units can cause a number of different issues such as power outages, short circuits, fires and other problems. When you encounter the H1 error code on your device’s screen, then you might be experiencing one of these issues.

Usually, your owner's manual would include all the information you need to know regarding common error codes found. However, the H1 error code is generally meant to signal that the AC unit has automatically turned on its Defrosting mode. Defrosting is done to improve the efficiency of the AC unit. The Defrost mode will divert any heavy heat source away from the indoor AC unit and will instead focus it on the outdoor unit (or vice versa, in some cases).

Unlike what you may assume, this code doesn't actually require any interference. In fact, it can eventually go away on its own. But the process can take some time, depending on the condition of your AC unit. It's not uncommon for a Gree AC unit to have this code for quite some time before it actually goes away.

However, there's always a chance that the defrosting process experiences some malfunction mid-way. Make sure to check in periodically to see if the defrosting process has improved. Also, make sure to regularly clean the coils of your Gree AC unit. If the H1 error code is still present after some time, then you should contact a Gree service technician. A service technician can properly diagnose and fix your problem. In addition, they can tell you if your Defrost mode is still functioning properly and if it needs to be repaired or replaced.
